IP Blocked from old cert-manager version


I had cert-manager v0.4.0 set up on my kubernetes cluster and my IP got blocked due to it sending a large amount of requests. I have upgraded all of my cert manager instances to v0.5.2.

This is the error I am getting:

cert-manager Failed to verify ACME account: acme: urn:ietf:params:acme:error:rateLimited: Your IP,, has been blocked due to ridiculously excessive traffic. Once this is corrected you may request this be reviewed on our forum https://community.letsencrypt.org

Assuming the large throughput of requests is fixed in 0.5.2, do you mind unblocking the IP ( Thanks for your time!


Hi @ahaughtondf, I opened a ticket to unblock this IP. I'll update this thread when the change has been made.

Thanks for upgrading your cert-manager installation,
